Q: Drivers are always parking illegally on the shoulder of the exit ramp from Interstate 595 and U.S. 1 to the terminal roadway at Fort Lauderdale-Hollywood International Airport as they wait for family and friends to arrive. They do this right in front of signs every 20 feet that parking isn't allowed. What's being done to stop this problem?

—Lynn Berger, Hollywood

A: Airport officials and Broward sheriff's deputies are well aware of the problem.

From time to time, deputies will patrol the road and "shoo" drivers away or write tickets. The fine is $36 if you are pulled over by a deputy and cited under a county statute for improper parking. If a state trooper writes you a ticket under the state statute, the fine is $71.50.

From January through August, deputies wrote 4,076 tickets.

Drivers are urged to park in the airport's short-term garages, which charge $1 per 20 minutes, or park for free in the cellphone waiting lot.

But finding the cellphone lot may take a little patience with all the construction going on at the airport. The old way to get to the lot via South Perimeter Road off Griffin Road is closed for construction of the new south runway.

But you can still get to the lot from North Perimeter or by driving through the terminal roadway and following the signs for the cellphone lot.

Q: For the past two weeks, I've noticed the left turn arrow from eastbound Woolbright Road to northbound El Clair Ranch Road hasn't worked. Can you tell me what has happened and when it will be repaired?

A: Palm Beach County technicians inspected the signals and found them to be working properly.

Here's what you're experiencing: The signal is protective-permissive, meaning you get a green arrow to turn left followed by a green ball, which allows you to make left turns after yielding to oncoming traffic.

The arrow will only appear if you pull up to the intersection prior to eight seconds before the light changes. If you pull up with less than eight seconds, the arrow will not appear until the next cycle of the signal. County officials say this is standard for how protective-permissive signals operate.

Q: Exiting the southbound Sawgrass Expressway onto Oakland Park Boulevard, the traffic signal to turn right onto Flamingo Road has a red arrow. Does the stop-and-go red apply here, or does it mean no right turn on red?

—Raul Bengolea, Coral Springs

A: You can turn right on red from a solid red light or a red arrow, unless the intersection has a sign that says "No turn on red."

The red arrows are used as a reminder to drivers that they are in a right-turn only lane and can't go straight.
